OSKAR GRAUHERING, OF ESSEN-ON -THE-RUHR, GERMANY, ASSIGNOR TO FRIED. KRUPP AKTIENGESELLSOHAFT, OF ESSEN-ON-THE-RUHR, GERMANY.
GUN WITH SCREW ELEVATING MECHANISM AND ADJUSTABLE SIGHT DEVICE.
To all whom it may concern:
Be it known that I, OSKAR GRAUHERING, a subject of the Emperor of Germany, and a resident of Essen-on-the-Ruhr, Ruttenscheid,
Germany, have invented certain new and useful Improvements in Guns with Screw Elevating Mechanism and Adjustable Sight Devices, of which the following is a specifi cation. The present invention relates to guns with independent sight line, such as described in Patent 809,818 granted to Otto Lauber and Friedrich Stock, January 9, 1906, and in the United States Patent 813,97 9, February 27, 1906, and the object of the invention is to improve such guns so as to provide for a rough and fine adjustment of the sight device independently of the elevating mechanism. In the accompanying drawing, one embodiment of the invention is shown applied to a gun that corresponds to the embodiment shown in Figures 1 to 4 of Patent 813,979.
Fig. 1 is a vertical transverse section through a gun and its elevating mechanism, parts being shown in elevation. Fig. 2 is a section on the line 22, Fig. 1, on an enlarged scale and looking from the right Fig. 3 is a section on the line 3- 3, Fig. 2, looking from the left; Fig. 4 is a view corresponding to Fig. 2 with the positions of some parts changed; Fig. 5 is a view partly corresponding to Fig. 3, ,with the position of one part changed Fig. 6 is a section on the line 6-6, Fig. 3, looking from above, and Fig. 7 is a sectionon the line 7-7, Fig. 3, looking from above and with some parts omitted.
The devices which form the subject matter of United States Patent 809,818, and of United States Patent 813,979 will not be dej scribed in this specification as they are fully explained in said patent and patent application.
. A bushing C (Figs. 1 to 6) is screwed into the tubular projection a of a guide piece A for the attachment bar B (Figs. 1, 2 and 4). In the bushing C is rotatably mounted a second bushing D (Figs. 2 to 4 and 6) which serves as bearing for the shaft E of the adjusting worm e for the attachment bar B. The bore of the bearing for the shaft E is eccentric to the bore of the bushing C so that by turning the bushing D, the worm 2 can be brought out of engagement with the teeth 11 f the attachment bar. A ring f which is provided with a handle F (Figs. 1, 3, and

6) is rigidly secured on the lower end of the bushing D. The handle F projects through a slot 0 (Figs. 2', 4 and 6) in the bushing C, the slot permitting the handle to be turned 180. The end walls 0 and 0 (see in particular Fig. 6) of the slot 0 are so located that the worm e meshes with the teeth b of the attachment bar, when the handle F lies against the wall 0 while the worm is disengaged from the teeth when the handle lies against the wall a. A helical spring G (Figs. 2 to 4) having one end engaging the bushing C and having its other end engaging the ring f (Fig. 3), tends to hold the bushing D in the position shown in Figs. 2 and 6, in which the handle F lies against the wall 0 A bell-shaped bushing consisting of two parts H and H (see also Fig. 1) which have a screw-threaded connection with each other, is rigidly connected to the shaft E by means of the non-circular or squared portion 6 and a headed screw J (Figs. 2 to 5) engagingthe squared portion.
The bushing H, H is rotatably but nonslidably connected with a cylindrical head K (Figs. 2' to 5 and 7) on a shaft K (see also Fig. 1) which is connected to the gimbaljoint L of the jointed or flexible and longitudinally movable coupling L M M L (Fig. 1)
Which is described in the application Serial No. 280,100, and which is connected with the shaft connection 0 P leading to the handwheel N (Fig.1).
The head K is provided with a stepped bore (Figs. 3, 5 and 7) which extends at right angles to the shaft K and which has rotatably and slidably mounted therein a bolt R which is provided with an abutment T The outer end of the bolt is capable of entering into a bore 712 (Figs. 3, 5 and 7) in the sleeve 11 H A spring Q (Figs. 3 and 5) which is located in the large portion of the bore k and abuts against the offset therein, and against the abutment r of the bolt R, tends to move the bolt outwardly or, in other words, to hold it in the position in which the bolt R is within the bore 72. and the abutment 1 lies against the inner Wall of the bushing H H (Fig. 3). In this position of the bolt R, the shafts K and E are coupled together.
The abutment 1" extends downwardly in the form of a handle 7 (Figs. 1 to 5), for which a guide-slot 10 (Figs. 3, 5 and 7) is provided in the head K the slot permitting the bolt R to be shifted such a distance from the position shown in Fig. 8, that it passes out of engagement with the bore 72 At the end of the slot 75 towards the axis of the shaft K is a notch lc (Figs. 3, 4: and 7) which extends at right angles to the slot and into which the handle 1 can be swung when the bolt R is brough)t out of engagement with the bore 7L2 (Fig. 5
The sight device can be adjusted by means of the hand-wheels N S (Fig. 1) of the elevating mechanism, in the manner described in Patent 813,97 9 when the parts are in the position in particular illustrated in Figs. 2 and'3, that is to say, when the worm e is held into mesh with the teeth I) of the at tachment bar B by means of the spring G, and when the shafts K and E are coupled together through the medium of the bolt R and the bushing H H If now for some reason or the other, such as breakage, the shaft connection connected to the hand-Wheel N or the coupling L M M L do not permit adjustment of the sight-device by means of the hand-wheel N, the bolt R is first brought out of the bore 72, 0f the bushing H H and is thereupon secured in the disengaged position (Fig. 5) by swinging the handle 7 into the notch 7r. Byturning the bushing H H the sight-device can now be adjusted in the guide-piece A independently of the elevating mechanism, to the elevation that corresponds to the distance of the target, and the sight-device can subsequently be directed at the target by turning the hand-wheel N or S of the elevating mechanism.
If the distance that the attachment bar B is to be moved in the guide-piece A independently of the elevating mechanism, is great, the handle F is moved against the action of the spring G from the position shown in Fig. 6 to the position in which it lies against the wall 0 of the slot 0 and it is held in that position. The worm is now out of mesh with the teeth 6 of the attachment bar B (Fig. 4) and rough adjustment can be imia-rted to the attachment bar directly by and. This done, the handle F is released, and the spring G returns the worm e into engagement with the teeth b whereupon the fine adjustment of the attachment bar can be effected by turning the bushing H H. During the coupling and uncoupling of the worm e, the shaft E moves laterally and this movement is partaken of by the bushing H H the shaft K and the jointed and longitudinally movable coupling L M M L If the gun be limbered and it is desired. to bring the attachment bar into the traveling position, that is to say, the position in which the head of the attachment bar rests on the guide-piece A, it is most suitable to use the procedure employed for the rough adjustment of the sight-post as above described, that is to say, the worm e is first uncoupled and the attachment bar is thereupon moved directly by hand in the guide-piece A. This procedure is also possible when the coupling R H H is in the coupling position and the aforesaid insertion of the attachment bar can, therefore, also take place by normal use of the gun, that is to say, when the independent sight-line is employed.
Having now described my invention, what I claim as new is:
1. The combination with the gun, a sight device, an elevating mechanism for the gun, connected to the sight device to adjust the latter relatively to the gun during the adj ustment of the gun to maintain the sight at a substantially fixed angle to the horizon, and means for adjusting the angle of the sight device independently of the elevating mechanism, of additional means for adjusting the sight device.
